Benefits of technology

[0013]Embodiments of the present disclosure may minimize service interruption in transmitting and receiving data belonging to a particular bearer by using a WLAN carrier.
[0014]Also, embodiments of the present disclosure may enable a base station to confirm whether a user equipment is linked to a WLAN termination.

Problems solved by technology

However, due to limited frequency resources, a base station has limitation in transmitting and providing a large amount of data to multiple user equipments.
In general, a service provider pays excessive costs for securing the frequency resources and exclusively using the secured frequency resources.
Such an unlicensed frequency cannot be exclusively used by one or more particular service providers.

first embodiment

mitting UE Identification Information to WLAN AP (WLAN Termination)

[0128]A BS may transmit, to a WLAN AP (WLAN termination), identification information on a UE that has been determined to add a WLAN carrier.

[0129]For example, in step S610 of FIG. 6, the BS may include, in a request message for addition / modification, identification information for the WLAN AP to identify the UE and transmit the request message to the WLAN AP. Then, in step S650 of FIG. 6, the UE performs association (e.g., authentication or access) with respect to the WLAN AP. In this case, the UE may include UE identification information for identifying the UE in the request message for addition / modification. Alternatively, after step S650 of FIG. 6, the UE may include, in a control plane message, UE identification information for identifying the UE. Alternatively, after step S650 of FIG. 6, the UE may include, in a user plane message, UE identification information for identifying the UE.

[0130]The WLAN AP may confir...

second embodiment

itting UE Identification Information by WLAN AP (WLAN Termination)

[0140]A WLAN AP may assign UE identification information to be used for access / authentication / association with respect to a WLAN, and the WLAN AP may deliver the UE identification information to a UE through a BS.

[0141]Specifically, while the WLAN AP transmits a response / confirmation message to the BS at step S620 of FIG. 6, the WLAN AP may include UE identification information UE in the response / confirmation message and transmit the response / confirmation message to the BS, where the UE identification information is used for the WLAN AP to identify the UE. Thereafter, while the UE performs association (e.g., access or authentication) with respect to the WLAN AP at step S650 of FIG. 6, the UE may perform the association based on the UE identification information UE. The WLAN AP may confirm information on whether the UE has succeeded in the association between the UE and the WLAN AP, by using the above-described UE iden...

third embodiment

Transmitting UE Identification Information to WLAN AP (WLAN Termination) Through UE

[0147]A BS may deliver UE identification information to a WLAN AP through a UE. However, in this case, the WLAN additional configuration procedure and a partial procedure of FIG. 6 may be changed. Accordingly, in the third embodiment, confirming, by using UE identification information, whether association is successful will be described with reference to a WLAN additional configuration procedure of FIG. 10.

[0148]FIG. 10 is a view illustrating a procedure for additionally configuring a WLAN carrier according to still another embodiment of the present disclosure.

[0149]Hereinafter, the procedure will be described in detail with reference to FIG. 10.

[0150]1) The BS 200 transmits an RRC connection reconfiguration message, which includes additional configuration indication information for additionally configuring a WLAN, to the UE 220 in step S1010.

[0151]As an example, the additional configuration indicatio...

Abstract

The provided is a method and apparatus for adding a WLAN carrier to an E-UTRAN carrier at a radio access network (RAN) level to transmit and receive data. The method may include: receiving, from a base station, additional configuration indication information for additionally configuring a WLAN carrier; additionally configuring the WLAN carrier on the basis of the additional configuration indicating information; and attempting WLAN associating through the WLAN carrier using UE identification information, wherein a WLAN end transmits confirmation information for the WLAN association of the UE to the base station.
